The paper shows the possibility of using chlorophyll-synthesizing microalgae of Chlorella Vulgaris to purify biogas from carbon dioxide (CO2), hydrogen sulfide (H2S) and ammonia (NH3). Experimental dependences of the dynamics of CO2 uptake by microalgae under the action of H2S inhibitor and NH3 activator are presented. A mathematical description of the growth of biomass of microalgae Chlorella Vulgaris depending on the concentration of hydrogen sulfide and ammonia was obtained.

One of the areas of waste disposal of fermentation industries is anaerobic fermentation and biogas production, which becomes increasingly attractive for researchers not only because of the global energy crisis but also the environmental one. Biogas production is based on methane fermentation fundamentally different from other types of fermentation, which creates certain difficulties in its implementation on a large scale.

The issue of industrial water treatment and food waste disposal is particularly relevant, especially for the alcohol industry. The problem of wastewater treatment and waste accumulation in the process of alcohol production is due to high chemical and biological oxygen demand, specific colour and odour, a large number of suspended substances, low pH. Therefore, the choice of promising wastewater treatment technologies is of paramount importance to ensure the ecological safety of the environment.

Проведено оцінку використання органічних відходів для виробництва біогазу за умов гострої необхідності скорочення споживання традиційних енергоресурсів. Експериментально підтверджена можливість використання органічних відходів (кукурудзи, соломи, гілок, опалого листя, картопляного лушпиння) для виробництва біогазу. Досліджено вплив подрібнення фракції сировини та температурного режиму на вихід біогазу. Встановлено, що найбільший вихід біогазу з картопляного лушпиння.

The article discusses the results of studies of the methane production from cyan biomass based on the data obtained in the course of a laboratory experiments. The yield of biogas was calculated from the substrate per unit volume, and its energy properties were determined. Experimental data indicates the feasibility and economic viability of this biotechnology.

We have analyzed the ecological hazard that has emerged as a result of the construction of hydropower plants on the Dnieper, which became the cause of uncontrolled development of cyanobacteria. The environmental risks that are caused by the uncontrolled development of cyanobacteria and their biodegradability were studied. The efficiency of application of the known methods of suppression of mass development of the blue-green algae was analyzed. The amount of biogas that can be synthesized from cyanobacteria biomass of Kremenchug reservoir was estimated.
